  “Yes,” Kresh agreed uncomfortably,” but the Three Laws--”

  “The Three Laws are going to drive me mad,” Welton snapped. “I know the Three Laws as well as you do, and you need not recite them again like some bloody holy’ catechism. I swear, Kresh, you Spacers might as well face facts and admit that worship of those dismal Laws is your state religion. The answer to all problems, the end of all quests, can be found in the infinite good of the Three Laws. I say that if we just assume that the Three Laws make a robot attack on Leving impossible, I think we are missing a key point.”

  “And what might that be, Lady Welton?” Donald asked mildly. It passed idly through Kresh’s mind that it was well that Donald was around, if only to lubricate the wheels of conversation. Welton had obviously paused for the sole purpose of eliciting the question Donald had asked, but Kresh was hell-damned if he would give her the satisfaction of asking it.

  “A very simple point,” Tonya Welton replied. “With all due respect, Donald, robots are machines, and it is impossible for them to harm humans only because they are built in such a way to make that so. If all runcarts were built without a reverse gear, that would not render the construction of a machine with reverse gear impossible. A machine that is built one way can be built another. Suppose robots were built another way? What is to prevent it--if the builder decided not to follow your precious Three Laws? Would not the rock-hard belief that robots cannot commit such acts provide a perfect cover? The robot’s builder need not even run, for none will think to pursue.

  “One other point. This speechblock put on the staff robots, preventing them from saying who ordered them to go to the far wing of the labs that night. It seems to me that a mechanical device, an override circuit, would be more effective in setting an absolute block against speech concerning certain subjects than in giving an intricate series of orders to each and every robot. It would be easier to set up as well. And before you object that such a speechblock circuit would weaken the robot’s ability to obey the damned Three Laws, we are assuming that the attacker was not too fastidious about such things. Donald--how large a piece of microcircuitry would that take?”

  “It could be made small enough to be invisible to the human eye, and could be wired in anywhere in the robot’s sensory system.”

  “I’ll bet your people never even thought to look for a physical cause for the speechblock, did they? Go over a few of the lab robots with a microscope and see what you find. As to why the perpetrator would need to set blocks for multiple time periods--perhaps he or she wanted some privacy while using the lab’s facilities to make up the attacker robot--or even the robot suit you two are postulating, if you insist that all robots must obey the Laws.”

  There was an uncomfortable silence before Tonya continued. “Even if you do insist on that,” she said at last, “there are documented cases where Three Law robots did kill human beings.”

  Donald’s head snapped back a bit, and his eyes grew dim for a moment. Tonya looked toward him with some concern. “Donald--are you in difficulty?”

  “No, I beg your pardon. I am aware of--such cases--but I am afraid that the abrupt mention of them was most disturbing. The mere contemplation of such things is most unpleasant, and caused a slight flux in my motor function. However, I am recovered now, and I believe you can pursue your point without concern for me. I am now braced for it. Please continue.”

  Tonya hesitated for a moment, until Kresh felt he had to speak. “It’s all right,” he said. “Donald is a police robot, programmed for special resilience where the contemplation of harm to humans is concerned. Go on.”

  Tonya nodded, a bit uncertainly. “It was some years ago, about a standard century ago, and there was a great deal of effort to hush it up, but there was a series of incidents on Solaria. Robots, all with perfectly functional Three Law positronic brains, killed humans, simply because the robots were programmed with a defective definition of what a human being was. Nor is the myth of robotic infallibility completely accurate. There have doubtless been other cases we don’t know about, because the cover-ups were successful. Robots can malfunction, can make mistakes.

  “It is foolish to flatly assume that a robot capable of harming a human could not be built, or to believe that a robot with Three Laws could not inadvertently harm a human under any circumstances. For my part, I see the Spacer faith in the perfection and infallibility of robots as a folk myth, an article of faith, and one that is contradicted by the facts.”

  Alvar Kresh was about to open his mouth and protest, but he did not get the chance. Donald spoke up first.

  “You may well be correct, Lady Tonya,” the robot said, “but I would submit that the myth is a needful one.”

  “Needful in what way?” Tonya Welton demanded.

  “Spacer society is predicated, almost completely, on the use of robots. There is almost no activity on Inferno, or on the other Spacer worlds, that does not rely in some way upon them. Spacers, denied robots, would be unable to survive.”

  “Which is precisely the objection we Settlers have to robots,” Welton said.

  “As is well known, and as is widely regarded as a specious argument by Spacers,” Donald said. “Deny Settlers computers, or hyperdrive, or any other vital machine knit into the fabric of their society, and Settler culture could not survive. Human beings can be defined as the animal that needs tools. Other species of old Earth used and made tools, but only humans need them to survive. Deny all tools to a human, and you sentence that human to all but certain death. But I digress from the main point.” Donald turned to look at Alvar and then turned back toward Welton.

  “Spacer society,” Donald went on, “relies on robots, trusts robots, believes in robots. Spacers could not function if they had no faith in robots. For even if we are merely machines, merely tools, we are enormously powerful ones. If we were perceived as dangerous “--and Donald’ s voice quavered as he even suggested the idea--”if we were so perceived, we would be worse than useless. We would be mistrusted. And who but a lunatic would have faith in a powerful tool that could not be trusted? Thus, Spacers need their faith that robots are utterly reliable.”

  “I’ve thought about that,” Welton admitted. “I’ve observed your culture, and thought about it. Settlers and Spacers may be rivals in some abstruse, long-term struggle none of us shall ever live to see the results of--but we are also all human beings, and we can learn from each other.

  “Of course we came here hoping to convince at least some of you to do without robots. There is no point in pretending otherwise. I have come to see that we are not going to convert any of you. We Settlers could no more wean you away from robots than we could convince you to give up breathing. And I have concluded it would be wrong of us to try.”

  “I beg your pardon?” Kresh said.

  Tonya turned to Donald, stared into his expressionless glowing blue eyes. She reached and touched his rounded blue head. “I, personally, have concluded that we cannot change the Spacer need for robots. To do it would destroy you. To attempt it is hopeless. Yet I am more certain than ever that your culture must change if it is to survive. But it must change in some other way.”

  “Why would you care if we survive?” Kresh asked. “ And why should I believe you do?”

  Welton turned toward Kresh and raised her eyebrow. “We are here trying to pull your climate back from the edge of collapse. I have spent the last year in this sun-baked city of yours rather than back home. That should lend some credence to my claims of sincerity,” she said with a hint of amusement. “ As to why we should care about your culture--would it not strike you as the height of arrogance to assume yours was the only right way to live? There is value, and merit, in diversity. It may well be that the Settler and Spacer cultures together will accomplish things that neither could do by itself.”

  Kresh grunted noncommittally. “That’s as may be,” he said. “But I am no philosopher, and I believe we have covered all the ground we are going to regarding the Fredda
Leving case. Perhaps I can send Donald around sometime and the two of you could discuss the whichness of why together.”

  Tonya Welton either missed his sarcasm, which seemed unlikely, or chose to ignore it. She smiled and turned back to Donald. “If you’d ever like to come by,” she said, addressing the robot directly, “I’d be delighted.”

  “I look forward to the opportunity, Lady,” Donald said.

  Kresh clenched his teeth, not quite sure which of the three of them--Donald, Welton, or he himself--had most succeeded in infuriating Alvar Kresh.

  ARIEL’S eyes came to light, glowing yellow. She stepped down from her niche and crossed the room to where her mistress sat. Ariel took up the seat Donald had used.

  “Well, Ariel, what did you think of that?” Tonya asked.

  “I believe it may be easier to get Alvar Kresh to listen than to direct him. I am not a skilled judge of such things, but I do not think he was in the least bit impressed by your arguments regarding the possibility of a--a--robot assailant. Nor do I think he was entirely convinced that I was indeed dormant.”

  “Let’ s get something straight, Ariel. You may not be a judge of human psychology in general, but you know more about Spacer psychology than I ever will. I doubt I’ll ever understand them completely. You were built by them, designed by them, meant to fit into their world. You are the only product of that world I can trust to be loyal to me. You can stand next to me, watching and listening, while they ignore you completely. That’s why I value your opinion.”

  “Yes, ma’am. I appreciate all that. But might I ask--if they all ignore me, anyway, why did you order me to simulate dormancy?”

  “An insurance policy. Kresh was here as a cop, not a Spacer. If you were an even slightly active presence in the room, that could draw his attention to you. If I ordered you out, and you were missing, he might notice that absence, and that would draw attention to you. Besides, I wanted you listening.

  “By telling him I let you go dormant whenever you choose, I drew his attention to me, to the eccentric Settler who treated her robot like an equal. If he thought about you, it would likely occur to him that you had been with me whenever I visited Leving Labs. I do not want you in the hands of Spacer robopsychologists. I’m not the most skilled person in ordering robots. They might easily find ways of getting you to speak about the things I have ordered you not to discuss.”

  “Thank you, ma’am. I understand more fully now. But I must say once again, I do not think he was much impressed by your idea of a robot committing the attack.”

  “Good. I did not expect him to accept the idea. All I wanted to do was muddy the waters.”

  “Ma’am?”

  “I want him worrying about side issues, blind leads. I want to slow him down.”

  “Ma’am, I am afraid I do not understand.”

  “I need time, Ariel. You know as well as I do that I need time to find things out for myself. I have, ah--interests--I wish to protect. “

  Tonya Welton rose, crossed the room, and began pacing back and forth, her actions at last betraying the nervousness Ariel had known was there. “I have interests to protect,” she said again. “He is in hiding, Ariel,” Tonya said, and there was no need for her to speak the man’s name. “He won’t even accept messages from me. That proves something is wrong. He is in danger, and that danger could only increase if his connection to me were revealed at the wrong moment. And I strongly suspect that Alvar Kresh would take a special pleasure in destroying anything--or anyone--that I hold dear.”

  ALVAR Kresh was glad to get out of Welton’s office, to put it mildly. As the elevator arrived at ground level, and he no longer had to hold his claustrophobia in check, he found himself breathing a sigh of relief, and felt his spirits suddenly rise. His anger seemed to fade away into the blessedly open skies.

  “I fear our visit was not especially productive,” Donald said. “Madame Welton did not offer much in the way of useful information or insight, and I do not see what she learned from us that she could not have learned by our sending a data transmission. Nor can I see why our presence was needed at the Ironhead riot. Your deputies handled that without any need of your expertise.”

  “Donald, Donald, Donald,” Kresh said as they walked across the parkland toward their aircar.” And you call yourself a student of human nature. That meeting had nothing at all to do with the exchange of information. Human beings very often are not talking about what they are talking about.”

  “Sir?”

  “We were there not to assist in countering the Ironhead demonstration, but to witness it, and to get the clear message that the Leving case could make such encounters worse. If the populace of Hades gets the idea that Settlers are attempting to discredit robots by staging attacks that seem to be committed by robots, the Ironheads won’t be able to handle all the new recruits.”

  “But what concern is that of yours?”

  “I am in charge of keeping the peace, for one thing. But bear in mind that she chose to meet us on her turf. Up here, on the surface, the air is still smoky, and we’re near enough the perimeter of Settlertown that the air smells of desert again. Down below, all was serene and quiet, and the air was sweet. Another clear message: The Settlers have no reason to fear the rioters. The Settlers can hunker down in their artificial cave. But the citizens of Hades have no such option. And yet the current plans for terraforming all rely on the Settlers. In short, Tonya Welton was telling us we need her far more than she needs us,” Alvar Kresh said as they reached the aircar.

  Donald sat down at the controls and they took off. “Did it strike you as odd that she wished to know so much about the Leving case? After all, she has no responsibility to investigate crimes,” the robot said as he maneuvered for altitude.

  “Yes, I wondered about that. In fact, I rather got the impression that she was waiting for us to say something we didn’t, though the devil alone would know what that might be. I don’t know, Donald. Perhaps she has some genuine personal or professional interest in Leving’s well-being.”

  “I see,” Donald said, some trace of uncertainty in his voice. “But I don’t regard that as a sufficient explanation of Lady Tonya’s strong interest. Note that she scarcely asked at all about Fredda Leving herself. It was only the robotic aspect of the case that interested her. Why does she care so deeply about the case, and why does she regard it as so overwhelmingly important?”

  “I tell you what I think, Donald,” Kresh said as he watched the landscape below. “I think a Settler committed the crime, perhaps acting directly under Tonya Welton’s orders, precisely to set off more disturbances and give the Settlers an excuse to get off the planet. Bringing us in today during the riot was merely the first step in orchestrating that withdrawal.”

  “Might I ask your reasons for thinking that?” Donald asked impassively as he guided the aircar.

  “Well, first off, I don’t like Settlers. I know that’s not much of a reason, but there it is. And second, say what Tonya Welton will about this contingent of Settlers being trained to understand our ways and appreciate the Three Laws, I still can’t believe a Spacer would try any of the stunts that have been suggested to explain the attack. Think about them: building a remote-control device that mimicked a robot, strapping on robot feet and using a robot arm as a club, building and programming a special-purpose killer robot. No Spacer would do those things.

  “Welton was right about one thing--the Three Laws are close to being our state religion. Interfering with them, abusing them or the concept of robots in any way, would be close to blasphemy. There are times when I think our illustrious Governor Chanto Grieg is pushing so hard for change that someone’s going to bounce up and call him a heretic. Maybe it even goes deeper than that. I find the very idea of perverting robots to be stomach-turning. It’s like the prohibition against cannibalism or incest. I doubt any Spacer unbalanced enough to make the attempt would still be sane enough to do all the methodical planning required.

  “No. Onl
y a Settler would be stupid enough--well, all right, ignorant enough--to try and plant the idea that a robot could commit an act of violence. Any Spacer would know how deep and abiding the prohibition against that is.”

  Alvar stopped and thought for a minute. Suddenly a new and disturbing thought dawned on him. “In fact, that might well be the motive. Maybe the Settlers don’t want to leave. We’ve been too tied up with figuring how the attack was made to stop and wonder why anyone would want to attack Fredda Leving.”

  “I’m afraid I don’t follow you, sir,” Donald said.

  “Let’s just ignore all of Welton’s nonsense about respecting us as an alternate culture. She as much as said they came here as missionaries, hoping to convert us away from robots. The Settlers--this lot on Inferno, and all of them generally--are always casting about for ways to make the Spacer dependence on robots look like a weakness, instead of a strength. Trying to convince us to abandon robots. You spoke about the need for us to trust robots. Suppose the attack on Leving is the opening salvo in a campaign to make us afraid of our own robots?”

  “I see the point, sir, but I am forced to question the choice of Fredda Leving as the victim. Why would the Settlers attack their own ally?”

  Kresh shook his head. “I don’t pretend to understand their politics, but perhaps there is some sort of bad blood between Welton and Leving. Some sort of resentment, some sort of competition or disagreement between them. Jomaine Terach hinted at it. It must be tied up in this grand project we can’t be told about yet.

  “And I don’t think we’re going to get anywhere until we know what that’s about.”

  THREE hours later, Alvar Kresh sat at his desk, reading through the daily reports, making notes to himself on the status of this investigation, that application for promotion. By rights, he should have gone home to bed, allowed himself some rest. All told, he had gotten perhaps an hour’s sleep the night before. But he was too keyed up to sleep, too eager to leap back in and get on with the chase.
